It’s an irrational number just use a call
The answer is D. If you substitute those values for n, you should be able to find that 4 makes the expression equal to 6.
Use elimination method - I am eliminaing the y-variable.
1(5x + 8y = 16) → 5x + 8y = 16
4(6x - 2y = 54) → 24x - 8y = 216
Add equations: 29x = 232
Divide by 29: x = 8
Answer: x = 8
Answer: 11 degrees Celsius
Step-by-step explanation:
19 + 52 = 81. 81 - 1 x 5 = 76.
